Open it from the top first.
- Casing with a speaker in the top part
- Battery LiPo 604060 3.7V 7.4Wh 2000mAh
- a NanoPi NEO V1.4 PCB
- an antenna PCB
- aspect quite similar to RDV4 antennas
- red LED visible through PCB
ICOPY-X 20200828
LF_ANT_345uH±5%
HF_ANT_1.9uH±3%
Dual ANT V6.1.4
Center Freq:125K&13.56M
- a green multi-function PCB
ICOPY MAIN V1.5 D-2110
- Proxmark3
- USB-C and battery management
- Speaker driver
- LCD 1.3'' BL-133H01B Driver:ST7789 240x240 4-line SPI
- Seems it can be driven by the STM32 and by the NanoPi
- Inputs driver
- STM32F103C8T6, still to figure out
This is an ongoing short BoM of the ICs started from visual inspection of the PCBs.
